N/A pumps put out far more fuel than N/A's can handle lol.You'll need to turn your fuel down.Back when I was N/A I installed a reman N/A ip and I had to turn the fuel down a flat and a half to 2 flats or so from max.When I turned it down,I didn't lose an ounce of power but I gained a full power level from the pedal,whereas before the last 3/4 was just "blank" and just blew dark gray smoke.
N/A's are very sensitive and even their ip's provide enough juice for one of the common turbo kits.I maxed it out when I installed a banks turbo and had all the boost it was advertised for and a few more lbs even,as someone adjusted the wastegate before I bought it.It wasn't until I installed an intercooler where I wanted a bull moose.Then it was a perfect match (even then with a smoke puff limiter.)
